I think you misunderstood my comment: I didn't mean to add "scif2_clk" (which
is not used on Salvator-X), but "scif_clk", which is the external clock for all
(H)SCIF instances, provided by 14.7456 MHz crystal X1 on Salvator-X.
This is used to program the BRG in SCIF2 to exactly 115200 bps.
Gr{oetje,eeting}s,
